Seeing virtual while acting real: Visual display and strategy effects on the time and precision of eye-hand coordination

摘要: Effects of different visual displays on the time and precision bare-handed or tool-mediated eye-hand coordination were investigated in a pick-and-place-task with complete novices. All them scored well above average spatial perspective taking ability performed task their dominant hand. Two groups novices, four men women each group, had to place small object precise order centre five targets Real-world Action Field (RAF), as swiftly possible precisely possible, using tool not (control). Each individual session consisted display conditions. The conditions was counterbalanced between individuals sessions. Subjects looked at what hands doing 1) directly front ("natural" top-down view) 2) 2D fisheye view 3) undistorted 4) 3D stereoscopic (head-mounted OCULUS DK 2). It made sure that movements all image matched real-world space. One group looking images monitor positioned sideways (sub-optimal); other placed straight ahead (near-optimal). viewing significantly detrimental effects (seconds) (pixels) execution when compared "natural" direct viewing. More importantly, we find significant trade-offs within groups, interactions manipulation results shed new light controversial findings relative coordination, lead conclude differences camera systems adaptive strategies novices are likely explain these.
